Secure and Efficient Cluster Selection Mechanism Using Wimax

WiMAX technology is a telecommunications technology that offers transmission of wireless data via a number of transmission methods; such as portable or fully mobile internet access via point to multipoint links. As the size of a Wireless Network is much vast because of this the network containing number of base station and mobile station is divided in terms of clusters. Each cluster having a cluster head or the base station the controls all nodes of the network. A WiMAX can have a node with the mobility. The problem begins when a node moves from the cluster and when outside the range of Cluster head. In such case the control of that node shifted to other Cluster Head. This process is called head off machism. The resulted system is the scheme to elect the best cluster head for this node respective to the security and efficiently. In this work we have do some basic parameter changes i.e. number of packet transfer, last packet time, bit rate, byte rate, packet lost, and packet delay time while performing the selection of base station. The analysis is performed for having the effective throughput and the delay. Now we use the public key cryptography, RSA to implement and achieve the secure handoff. The analytical results shows that the use of WiMAX in handover during communication gives better efficiency.
